Samsung seems to constantly be updating its Ultra Edition line-up, this time with the D840, silver-coloured variant of the D900.

Made out of "cutting-edge featherweight materials", according to Samsung, it is a super lightweight slider with a silver finish.

It offers a 2.12-inch screen with 240x320 resolution, and measures just 11.9mm thick.

Multimedia features include a 2Mp camera with 4x digital zoom and flash, and enough memory to record up to an hour of video and an expandable memory slot.

Other features include a speakerphone, Bluetooth, USB, vCard and vCalendar, TV-Output, Offline Mode, and a document viewer.

The D840 will be available in February from either Vodafone, Orange and Carphone Warehouse.
